Failover in NAT

RodrigoB — Thu, 25 Mar 2021 01:51:05 GMT

We have a configuration to balance two NAT destinations, in the Translated Address we have a group with the two IP destination

We need to performing a failover if NAT # 1 192.168.251.21 stops working, passing to NAT # 2 192.168.251.22.

When the IP # 1 is turned off, so that it sends the traffic to IP # 2, it is still trying to go out on IP # 1

Is this configuration possible?

I don't get what exacltly you want by reading the description. Have you tested path monitoring?

Hello,

if i understond your question correctly, you already have route balancing mechnism configured , if so seems like both traffic matching the same NAT rule.

NAT rules need to have what to diffrentiate in "Traffic Matching" between them, that means for example you will need different destionations zones or destionations interfaces...
